Jimmy Kimmel: "My Head Is Still Spinning" From Charlie Sheen Kiss

"We had a very very famous surprise walk-on guest tonight. My head is still spinning," Kimmel tweeted after the two kissed on-air. "Legend has it that if Charlie Sheen kisses you at midnight, you turn into a whorewolf."

Sheen's take on the lengthy lip-lock? "Your lips are very moist," he told Kimmel, 43.

The former Two and a Half Men actor, 45, then gifted several audience members (and scheduled guest MarkCuban) with "Winning" and "tiger blood" T-shirts before presenting Kimmel with a mug. "It's got a fox on it," he explained.
